Improved estimators in Bell regression model with application
Solmaz Seifollahi, Hossein Bevrani, Zakariya Yahya Algamal
In this paper, we propose the application of shrinkage strategies to estimate coefficients in the Bell regression models when prior information about the coefficients is available.…
